UHPFRCs displayed strain-hardening responses, in both shear and tensile testing, accompanied with multiple microcracks.
These facets are the result of multiple microcracks emanating at 45 degrees from the notch and linking together as the crack propagates.
ECC achieves high ductility by forming multiple microcracks with crack width less than 60 μm under tension.
In this paper, SHCC specimens were preloaded under three-point bending to introduce multiple microcracks and exposed to different conditions to assess their self-healing.
The collective growth of multiple microcracks (or short cracks) during low cycle fatigue of polycrystalline Cu 30%Zn, 316L and Fe 26Cr 1Mo is investigated.
At high stress ratios (R>0.7), a transition of failure mode occurs from traditional surface fatigue crack initiation and growth to bulk-dominated damage initiation and coalescence of multiple microcracks consistent with a ductile tensile test.
Multiple microcracks with a crack spacing of less than 7.7 mm were observed.
Multiple response signal-to noise ratio.
Over multiple response opportunities, recall may be inconsistent.
